A classic cocktail that was created in New York City in the 1940s, Moscow Mule consists of vodka, ginger beer, and lime juice. Because it contains ginger beer, Moscow Mule is a type of buck (a mixed drink with ginger beer or ale, spirit, and citrus), so it is often referred to as Vodka Buck.
The cocktail is traditionally served in a copper mug, on the rocks, with a lime wheel garnish. Vodka is typically associated with Russia, while mule was supposedly added to the name because ginger beer adds a kick of flavor, hence the name Moscow Mule.
